METHOD FOR SPHEROISIZING CYCLIC NITRAMINE CRYSTALS Russian patent published in 2018 - IPC C30B30/06 C30B29/54 C30B29/60 C06B21/00

Abstract RU 2674970 C1

FIELD: blasting operations.

SUBSTANCE: invention relates to explosives, namely to the field of spheroidization of crystals of cyclic nitramines. Method is described for the spheroidization of cyclic nitramine crystals, which includes stirring suspension of nitramine in liquid working medium, characterized in that stirred suspension is subjected to ultrasonic treatment, and aliphatic alcohol, or water, or solvent of class of alkanes, or a solvent of class of chlorine-containing alkanes, or a solvent of class of aromatic hydrocarbons, is used as liquid working medium.

EFFECT: method for spheroidizing crystals is proposed, characterized by increased manufacturability and yield of target product by reducing duration of processes and minimizing formation of fine dispersed fraction.
